This survey presented a discussion of the existing scaling factor and adaptive scaling factor
in image watermarking schemes. The discussion included several issues: robustness …

Digital watermarking techniques can be used to solve the authenticity and copyright
protection issue of images. In this work, the authors have proposed an adaptive color image …

Image watermarking technique is an alternative solution to protecting digital image
copyright. This paper proposed a new embedding technique based on different embedding …

Diagnosis aims at predicting the health status of components and systems. In photovoltaic
systems, it is vital to guarantee energy production and extend the useful life of photovoltaic …

Imperceptibility, robustness, security and capacity are the main features of a digital image-
watermarking scheme, and their simultaneous acquisition is a challenging problem. In the …

Modified wavelet called wavelet packet transform (WPT) based approach is proposed in this
paper for the detection of different disturbances occurring due to faults in grid-connected …

Digital images have become an important way of transmitting information, and the risk of
attacks during transmission is increasing. Image watermarking is an important technical …

Digital watermarking is an effective technique for image copyright protection. Many digital
image watermarking algorithms are sensitive to geometric distortions. These distortions …

Current vector map zero-watermarking algorithms that integrate blockchain technology
typically focus on a limited subset of feature classes within datasets, resulting in significant …

A novel adaptive secure holographic image watermarking method in the sharp frequency
localized contourlet transform (SFLCT) domain is presented. Based upon the sine logistic …
